2 W A R N I N G S ANY ALTERATION TO THE ORIGINAL DESIGN, INSTALLED OTHER THAN AS SHOWN IN THESE INSTRUCTIONS, OR USED WITH A TYPE OF GAS NOT SHOWN ON THE RATING PLATE IS PROHIBITED AND VOIDS THE WARRANTY. The installation must conform to local codes. In the absence of local codes, the installation must conform to the National Fuel Gas Code, also known as NFPA 54 and ANSI Z latest edition. Installation and service must be performed by a qualified installer (i.e., a licensed heating contractor or gas company personnel). Read this Installation and Owners Guide carefully and completely before attempting to install, operate or service this heater. Improper use of this heater can result in serious bodily injury or death due to hazards of fire, explosion, electrical shock or carbon monoxide poisoning. When used without fresh air, this heater may give off CARBON MONOXIDE, an odorless, poisonous gas. CARBON MONOXIDE POISONING MAY LEAD TO DEATH! Early signs of carbon monoxide poisoning resemble the flue with headache, dizziness and/or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once, and have the heater serviced. Some people such as pregnant women, persons with heart or lung disease, anemia, those under the influence of alcohol, and those at higher altitudes are more affected by carbon monoxide than others. Retain this manual for future reference. It is your guide to many years of a proper and safer operation of the heater. 1. This is a heating appliance any safety screen or guard removed for servicing an appliance must be replaced prior to operating the appliance. 2. Children and adults should be alerted to the hazard of high surface temperatures and should stay away to avoid burns or clothing ignition. 3. Young children should be carefully supervised when they are in the room with the heater. 4. Do not install this heater at altitudes above 5000 ft. because shutdown of the heater by the ODS system may occur due to reduced oxygen levels at these altitudes. 5. This appliance is only for use with the type of gas indicated on the nameplate. THIS APPLIANCE IS NOT CONVERTIBLE FOR USE WITH OTHER GASES. Please check the gas type shown on the heater nameplate prior to hooking the heater to the gas supply. 6. DO NOT install this heater in bedrooms or bathrooms. The maximum input for use in bathrooms in 6,000 Btu/hr and 10,000 Btu/hr in bedrooms where not prohibited by local codes. 7. LPG containers (Propane cylinders) must not be used or stored indoors. 8. DO NOT install this heater directly onto an LPG container or propane cylinder without directions from your propane company because high gas pressure can damage this heater. 9. Always operate the heater at the OFF, P or one of the three locked positions. Never operate the heater at any setting between these locked positions, as this may result in improper combustion. 10. DO NOT locate this heater in high traffic areas or in windy or drafty locations. 11. Keep the area near the heater free from combustible materials, gasoline, and other flammable vapors and liquids. 12. DO NOT use this heater if any part has been under water. Immediately call a qualified service person to inspect the room heater and to replace any part of the control system and any gas control that has been under water. 13. This heater has a pilot light safety system that turns off the heater if enough fresh air is not available. The pilot light safety section on this unit does not sense the presence of carbon monoxide. It senses the depletion of the oxygen supply used in the combustion process. Combustion of gas with a depleted -1-

3 oxygen supply is one source of carbon monoxide. 14. If this heater is installed in a room having a high vertical dimension, a fan to circulate the air is recommended to improve the comfort level in the room. When a fan is used to circulate air, it should be located so that the airflow is not directed at the burner. 15. If installed in a garage, this heater must be wall mounted only. The bottom of the heater must be a minimum of 18" above the finished floor. 16. A vent-free gas heater will increase the amount of humidity in the room in which it is installed. 17. A fresh air opening for combustion and ventilation air must be provided in the room where the heater is installed. The opening must have at least one square inch of free air opening per 1,000 Btu/hr of gas consumption for the total input rating of all gas equipment in the space. 18. This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable codes. 19. The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 ft 3 per 1,000 Btu/hr (4.8 m 3 /kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 ft 3 per 1,000 BTU/Hr (4.8 m 3 /kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the space. 20. WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA54, Air for Combustion and Ventilation, or applicable codes. 21. WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code, ANSI Z223.1 / NFPA 54, the International Fuel Gas Code, or applicable local codes. 22. Unusually tight construction is defined as construction where: a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 perm (6x10-11 kg per pa-sec-m2)or less with opeings gasketed or sealed; b) Weather stripping has been added on openable windows and doors; and c) Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and other openings. -2-

4 COMBUSTION AND VENTILATION AIR REQUIREMENT WORKSHEET The purpose of this worksheet is to help you determine if you are planning to install this heater in an unconfined or a confined space. An unconfined space is one that is large enough to meet all the combustion and ventilation air requirements of all the fuel burning appliances to be in operation in this space. No additional air requirements are needed. A confined space is one that is not large enough to meet the combustion and ventilation air requirements for all the fuel burning appliances in that space. As a result, additional air is required in this space to meet the appliance needs. Check with your installer on ways to accomplish this, or use a smaller Btu/hr input heater. STEP 1: Determine the volume of the space in which the heater is to be installed. Include adjoining rooms with doorless passageways. Example: 24' (long) x 16' (wide) x 8' (high) = 3072 ft 3. LENGTH x WIDTH x HEIGHT = Ft 3 STEP 2: Multiply the volume of the space (calculated in Step 1) by 20 Btu/hr to determine the maximum Btu/hr that the space can support without additional combustion and ventilation air provided. Result from Step 1 x 20 Btu/hr = Btu/hr STEP 3: Add the Btu/hr inputs of all fuel burning appliances in this space. NOTE: DO NOT include Direct-Vent gas appliances because these have sealed combustion systems that draw combustion air from outdoors. Examples of appliances to consider include: gas ranges, gas water heaters, gas logs, kerosene heaters, etc. Proposed Vent-Free Heater Fuel Burning Appliance #1 Fuel Burning Appliance #2 TOTAL Btu/hr Btu/hr Btu/hr Btu/hr STEP 4: Compare the results from Step 2 and Step 3. If the result from Step 2 is greater then the result from Step 3, the area where the heater is to be installed can be classified as an unconfined space. This means that the space is capable of handling the combustion and ventilation air requirements of the existing fuel burning appliance(s) and the proposed heater. If the result from Step 2 is less than the result from Step 3, the area where the heater is to be installed is classified as a confined space. This means that either additional combustion and ventilation air must be provided into this space (use one of the methods described in the National Fuel Gas Code, ANSI Z latest edition) or the size of the proposed heater must be reduced so that the above calculations show the space to be an unconfined space. -3-

5 SAFETY INFORMATION FOR USERS OF LP-GAS Propane (LP-Gas) is a flammable gas that can cause fires and explosions. In its natural state, propane is odorless and colorless. You may not know all the following safety precautions, which can protect both you and your family from an accident. Read them carefully now, then review them point by point with the members of your household. Someday when there may not be a minute to lose, everyone's safety will depend on knowing exactly what to do. If, after reading the following information, you feel you still need more information, please contact your gas supplier. LP-GAS WARNING ODOR If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas. That's your signal to go into immediate action!! Do not operate electric switches, light matches, or use your telephone. Do not do anything that could ignite the gas.! Get everyone out of the building, vehicle, trailer or area. Do that IMMEDIATELY.! Close all gas tank or cylinder supply valves.! LP-Gas is heavier than air and may settle in low areas such as basements. When you have reason to suspect a gas leak, keep out of basements and other low areas. Stay out until firefighters declare them safe.! Use your neighbor's telephone and call a trained LP-Gas service person and the fire department. Even though you may not continue to smell gas, do not turn on the gas again. Do not reenter the building, vehicle, trailer or area.! Finally, let the service man and firefighters check for escaped gas. Have them air out the area before you return. Properly trained LP-Gas service people should repair the leak, then check and relight the gas appliance for you. NO ODOR DETECTED - ODOR FADE Some people cannot smell well. Some people cannot smell the odor of the chemical stench put into the gas. You must find out if you can smell the odorant in propane. Smoking can decrease your ability to smell. Being around an odor for a time can affect your sensitivity or ability to detect that odor. Sometimes other odors in the area mask the gas odor. People may not smell the gas odor or their minds are on something else. Thinking about smelling a gas odor can make it easier to smell. The odorant in LP-Gas is colorless, and it can fade under some circumstances. For example, if there is an underground leak, the movement of the gas through soil can filter the odorant. Odorants in LP-Gas also are subject to oxidation. Odor fading can occur if there is rust inside the storage tank or in iron gas pipes. The odorant in escaped gas can adsorb or absorb onto or into walls, masonry and other materials and fabrics in a room. That will take some of the odorant out of the gas, reducing its odor intensity. LP-Gas may stratify in a closed area, and the odor intensity could vary at different levels. Since it is heavier than air, there may be more odor at lower levels. Always be sensitive to the slightest gas odor. If you detect any odor, treat it as a serious leak. Immediately go into action as instructed above. SOME POINTS TO REMEMBER Learn to recognize the odor of LP-Gas. Your local LP-Gas Dealer can give you a "Scratch and Sniff" pamphlet. Use it to find out what the propane odor smells like. If you suspect that your LP-Gas has a weak or abnormal odor, call your LP-Gas Dealer. If you are not qualified, do not light pilot lights, perform service, or make adjustments to appliances on the LP-Gas system. If you are qualified, consciously think about the odor of LP-Gas prior to and while lighting pilot lights or performing service of making adjustments. Sometimes a basement or a closed-up house has a musty smell that can cover up the LP-Gas odor. Do not try to light pilot lights in the area where the conditions are such that you may not detect the odor if there has been a leak of LP-Gas. Odor fade, due to oxidation by rust or absorption on walls of new cylinders and tanks, is possible. Therefore, people should be particularly alert and careful when new tanks or cylinders are placed in service. Odor fade can occur in new tanks, or reinstalled old tanks, if they are filled and allowed to sit too long before refilling. Cylinders and tanks that have been out of service for a time may develop internal rust, which will cause odor fade. If such conditions are suspected to exist, a periodic sniff test of the gas is advisable. If you have any question about the gas odor, call your LP-Gas dealer. A periodic sniff test of the LP-Gas is a good safety measure under any condition. If, at any time, you do not smell the LP-Gas odorant and you think you should, assume you have a leak. Then take the same immediate action recommended above for the occasion when you do detect the odorized LP-Gas. If you experience a complete "gas out" (the container is under no vapor pressure), turn the tank valve off immediately. If the container valve is left on, the container may draw in some air through openings such as pilot light orifices. If this occurs, some new internal rusting could occur. If the valve is left open, then treat the container as a new tank. Always be sure your container is under vapor pressure by turning it off at the container before it goes completely empty or having it refilled before it is completely empty. -4-

8 INSTALLATION TO GAS SUPPLY 1. The gas supply must comply with local codes, or in their absence, the installation must be in accordance with the American National Standard (National Fuel Gas Code) NFPA 54, also known as ANSI Z latest edition, available from the ANSI, Inc., 1434 Broadway, New York, New York 10018, or the National Fire Protection Association, Batterymarch Park, Quincy, MA WARNING: When using LP gas, this heater requires an external regulator (not supplied) located between the heater and LP Supply Tank. This regulator must be supplied by the installer to reduce incoming LP Gas pressure to a maximum of 14 inches of water column. Under no circumstances should this heater ever be hooked directly to an LP supply tank. IMPORTANT: The Pressure Regulator must be held with a wrench when connecting gas piping and/or fittings to the Pressure Regulator. 3. Use only new, black iron or rust resistant steel pipe. Copper tubing may be acceptable in certain areas. CHECK LOCAL CODES TO DETERMINE ACCEPTABLE TYPES OF GAS PIPING. 4. The gas supply line shall be sized and installed to provide a sufficient supply of gas to meet the minimum demand of the heater without undue loss of pressure. Typical Installation Supply Line Up to 20,000 Btu/hr 3/8" or greater Up to 30,000 Btu/hr 1/2" or greater 5. The sealant used on the threaded pipe joints of the gas pipe must be the specific type resistant to the action of Liquid Petroleum Gas. Apply sealant lightly to male threads to ensure excess sealant does not enter lines. Any excess sealant could be forced into the pipe and result in clogged gas valves. 6. The supply system must include a manual shut-off valve, a union in the line, and a plugged 1/8" NPT tap. The tap should be accessible for test gauge connections upstream of the gas supply connection to heater. 7. Include a drip leg (trap) in the supply line. The purpose of the drip leg is to prevent moisture and contaminants in the gas supply from entering the heater controls. The drip leg should be readily accessible to permit cleaning or emptying. A drip leg should not be located where the condensate is likely to freeze. Failure to use a drip leg can result in operational difficulties in the heater. GAS SUPPLY CHECK A union must be provided directly at the gas inlet to the heater. A manual gas valve must be provided upstream of the union. This will allow you to shut off the gas supply to the heater if it is necessary to remove it for service purposes. The appliance and its appliance main shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig. (3.45kPa). The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.45kPa). The connectors must be checked and cleaned before assembling and then wrenched up tight for a gas tight connection. Apply a soap and water solution to all joints and watch for bubbles to check for gas leaks. NEVER USE ANY OPEN FLAME TO CHECK FOR GAS LEAKS. HEATER MAINTENANCE - PERIODIC VISUAL CHECK The burner must glow evenly over the entire surface when operating correctly. The pilot flame must burn with a clear blue flame. See Figures 3 and 4. (18,000 Btu/hr input model shown) HEATER SERVICE SATISFACTORY Proper Burning Figure 3 UNSATISFACTORY Satisfactory Proper Burning Figure 4 Unsatisfactory To service the heater, turn off the gas supply and disconnect the gas piping at the union. Unscrew the two screws located in the lower front part of the unit. By sliding the panels upwards and toward the front, the functional elements of the unit are uncovered. Periodic cleaning of the unit is required. Dust the surface of the unit and vacuum clean burner surfaces and the control compartment. -7-

9 BURNER If this heater has an optional blower, disconnect the electrical connection before servicing the heater (e.g., unplug the blower). Keep the heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids. If you need to replace the burner assembly, loosen screws A and B, unscrew the tubing fittings C, and disconnect the assembly, see Figure 5 (18,000 Btu/hr input model shown). A dust out of the pilot assembly. Sometimes just blowing air back through the pilot will get rid of the dirt. If that fails to solve the problem, remove the wire clip that holds the metal strip onto the pilot assembly. Remove the cover and blow any dust out. Reassemble and check for proper operation. If that fails, the pilot assembly should be removed and air blown through the assembly and gas line as shown in Figure 6. To prevent damage to this assembly, follow the instructions below for disassembly and assembly of the ODS for cleaning. WARNING: Never use needles, wires, or similar cylindrical objects to clean the pilot orifice. This will only damage the calibrated ruby orifice (about the size of the head of a pin) which controls the pilot gas flow.
